6 Claims.

This invention relates to a device adapted to be used by carpenters,cabinet makers and the like for measuring, gauging and laying outmortises and the like for installation of door locks; hinges,

butts, and the like and comprises a member adapted to be placedalongside a door casing or on a door for laying out mortises for theinsertion of locks, hinges, butts and the like which not only providesmeans for accurately measuring the space to be occupied by the hardware,but also provides means for forming a furrow along the edge of the doorcasing or door to indicate the depth of out of said mortise. Said furrowforming means are adjustable to suit any required thickness of hinge andthe like.

Means are also provided on the end'of the tool frame for forming afurrow along the edge of the door casing or the door for extremely thinhinges and other hardware, or in any places where the spot to be markedis inaccessible with the main portion of the tool.

Some of the objects of the invention having been stated, the structurewill appear more fully as hereinafter explained when taken in connectionwith the accompanying drawing, in which Figure 1 is a plan view of mytool adjusted for laying out mortises for the insertion of locks;

Figure 2 is an edge view of Figure 1 looking from the lower side ofFigure 1;

Figure 3 is an opposite edge view of the tool looking at the upper sideof Figure 1;

Figure 4 is an enlarged cross sectional view taken along the line 44 inFigure 1;

Figure 5 is an end view of the tool looking at the right-hand end ofFigure 1.

Referring more particularly to the drawing, th numeral 10 indicates oneportion of the stock of my tool having cavities 11 and 12 transverselythereof and also having a central cavity 13 having a hole 14communicating with the outside of member 10 and with cavity 13. Theupper portion 15 of the stock has somewhat narrower cavities 16 and 1'7coinciding with cavities 11 and 12. The portion 15 also has a cavity 18coinciding with cavity 13, and in the bottom of cavity 18 there is acircular cavity 19 having a hole 20 extending from the base of saidcavity 19 to the exterior of member 15. Member 15 also has cavities 21and 22 therein in which are mounted coiled springs 23 and 24. Theportions 10 and 15 are secured to each other by any suitable means suchas screws 25 and 26.

Slidable gauge 2'7 has legs 28 and 29 slidably mounted in cavities 11and 12 which legs are nor- ,mally pressed against the bottom of saidcavities 11 and 12 by the coiled springs 23 and 24. The gauge 27 alsohas a central portion 30 having markings 31 in sixteenths of an inchreading; from point 43, while leg 28 has markings 32 ex-' tending alongthe exterior thereof and reading from the corner 33, whereas themarkings 34 on leg 28 read from corner 35. i

Suitable slots 36 are provided for marking a center line of a mortisefor looks and the like. Leg 29 has slots 40a therein adapted tocooperate with slots 36 in leg 28 for marking a center line for a lockmortise. Leg 29 has markings 40 extending along the exterior thereofbeginning at l the corner 41, whereas, markings 42 occur on the;

inside portion of leg 29 reading from 0011161741370 Slidably mounted incavities 16 and 1'7 are the legs 45 and 46 of another gauge havingportion 47 joining legs 45 and 46. Set screws 47a and 48 are adapted topress legs 45 and 46 together with, iegs 28 and 29 toward member 10 tohold them 76, in adjusted position. Leg 45,has graduations 50 along theinside thereof beginning at corner 51, whereas, leg 46 has-'graduations52 thereon reading from corner 53, Whereas portion 4'7 has graduations54 thereon reading from corner 53. Portion 15 has a beveled face 56having graduations 5'7 thereon. a v

. Member 10 also has a sloping cavity 60 coinciding with cavity 13 inwhich a blade 61 is adapted to have movement, said blade 61 havinga slot62 therein penetrated by bolt 64 around which is loosely mounted acompression spring 65 normally forcing blade 61 against the head ofscrew 64. By means of screw 64 the distance of blade 61 can be adjustedwith relation to the gauge 90, 27 and by the aid of graduations 6511 thethickness of a hinge and the like can be determined. Screw 64 may beadjusted by means of inserting a screw driver thru hole 14.

Threadably secured in one end of member 15 is a screw 70 having a sharpedge '71, said'screw 70 is held in adjusted position by means of a setscrew '72. Screw '70 may be used for forming a furrow to indicate depthof cut for a very thin hinge or butt in places inaccessible to blade 61or in case of very thin hinges or butts.

When a marking for a. hinge mortise is to be marked out, the top gaugeis slid outwardly until portion 4'7 coincides with portion 30 and apencil marking is made along the inner edges of portions 28, 29 and 30of member 27 to define the boundry for the mortise for a hinge, butt andthe like.

In order to mark a boundary for a hinge mortise it might be added thatonly one of the squares is needed; therefore, by making portions 30 and47 coincide only one of the gauges is visible and the tool will occupythe minimum amount of space when in this position. When these members 30and 47 are moved outwardly until the distance from the points 35, 43 or51 and 53 to the cutting edge of blade 61 is slightly less than thewidth of one of the leaves of the hinge the outside boundaries or thehinge leaf are inscribed by marking along the inside edges of members28, 29 and 30. It will be seen that gauges 57 and 54 are provided tomark the length of the mortise for the hinge.

To get the depth that this mortise is to be cut,

blade 61 is adjusted by means of screw '64 so that the distance from thecutting edge toth'e. face of portions 28 and 29 is exactly the same asthe thickness of the hinge leaf. Then by giving the back portion ofblade 61 a light tap the depth'that the mortise is to be cut isdesignated on the side or the door.

Let us suppose that we wish to mark the outline of a mortise on the edgeof a door in order that the sanie'may'be chiseled out for the receptionof a lock. To perform this operation with niy working;tool it will benecessary for screw 64 to be loosened'to allow blade 61 to be movedinwardly so that the cutting edge will not project beyond the edge ofopening 60. Then the lower face of member 10 (Fig. 4) is placed againstthe face or the door with the gauges 30 and 47 resting on the edge ofthe door where the outline of the -mortise is to be marked. When thegauges have been adjusted for marking the outline, their positions willbe approximately as shown in Figurefli and then with a pencil or marker,using the inside edges of portions 30, 28 and 29 and the outside edgeof-portion 47; a rectangular outline is inscribed on the edgeof thedoonThen a marker'is inserted in one of the slots 36 or 4021 that happens tobe on the longitudinal center line of the rectangle and by sliding thetool on the: edge of the door the center line is marked, Markings 31 and54 are provided so that a rectangle of any desired length may beinscribed by using these readings.
